Hikohikongā hau motuhakeHe peka nui ēnei o ngā hau motuhake. Ka uru atu rātou ki roto i ngā hononga katoa o te hanga hau ā-irahiko, ā, he rauemi mata nui hoki mō te hanga o ngā ahumahi hiko pēnei i ngā ara iahiko whakauru tino nui, ngā taputapu whakaatu papatahi, me ngā pūtau rā.

I roto i te hangarau haurua-ira, e whakamahia whānuitia ana ngā hau kei roto te fluorine. I tēnei wā, i roto i te mākete hau hiko o te ao, e 30% o te katoa o ngā hau hiko kei roto te fluorine. He wāhanga nui ngā hau hiko kei roto te fluorine o ngā hau hiko motuhake i roto i te mara o ngā rauemi mōhiohio hiko. Ka whakamahia whānuitia ēnei hei horoi me hei whakairo, ā, ka taea hoki te whakamahi hei tāpiri, hei rauemi hanga kiriata, me ētahi atu. I roto i tēnei tuhinga, ka arahina koe e te kaituhi ki te mārama ki ngā hau kei roto te fluorine.

Ko ngā hau kei roto he fluorine e whakamahia whānuitia ana ēnei e whai ake nei

Hauota toru-pūhaumāota (NF3): He hau e whakamahia ana hei horoi me te tango i ngā paru, e whakamahia ana mō te horoi i ngā rūma tauhohenga me ngā mata o ngā taputapu.

Hexafluoride whanariki (SF6)He kaihopu whakapūhau e whakamahia ana i roto i ngā tukanga whakatakoto waikura, hei hau ārai hoki mō te whakakī i ngā mea ārai.

Hauwaiwaihā (HF): Whakamahia hei tango i ngā waikura mai i te mata o te silicon, hei mea whakairo hoki mō te whakairo i te silicon me ētahi atu rauemi.

Hauota pūhaumāota (NF): Whakamahia hei keri i ngā rauemi pēnei i te silicon nitride (SiN) me te konumohe nitride (AlN).

Trifluoromethane (CHF3) metetrafluoromethane (CF4)Hei keri i ngā rauemi whai pūhaumāota pērā i te pūhaumāota silicon me te pūhaumāota konumohe.

Heoi anō, he tūponotanga anō ō ngā hau kei roto he wheowhio, tae atu ki te paitini, te waikura, me te mura.

Paitini

He paitini ētahi hau kei roto he pūhā, pērā i te hauwai pūhā (HF), he tino whakapataritari tōna kohu ki te kiri me te ara manawa, ā, he kino hoki ki te hauora o te tangata.

Te waikura

He tino waikura te hauwai pūhaumāota me ētahi pūhaumāota, ā, ka pā kino kino ki te kiri, ki ngā kanohi me te ara manawa.

Te mura

He mura ētahi o ngā pūhaumāota, ā, ka tauhohe ki te hāora, ki te wai rānei i te rangi ka tuku i te wera nui me ngā hau paitini, ka puta ai he ahi, he pahūtanga rānei.

Tūponotanga pēhanga teitei

Ka pahū ētahi hau whai wheori i raro i te pēhanga teitei, ā, me tino tupato ina whakamahia, ina rongoatia hoki.

Te pānga ki te taiao

He roa te ora o ngā hau kei roto te pūkawai i te āhuarangi, ā, he nui hoki ngā uara GWP, ā, ka pā kino ēnei ki te paparanga ozone o te āhuarangi, ā, ka pā pea te mahana o te ao me te parahanga o te taiao.

Kei te hohonu haere tonu te whakamahinga o ngā hau i roto i ngā mara hou pēnei i te hikohiko, ā, ka nui ake te hiahia mō ngā hau ahumahi. I runga i te nui o te kaha whakaputa hou o ngā wāhanga hiko nui pēnei i ngā semiconductors me ngā panera whakaaturanga i Haina matua i roto i ngā tau torutoru e whai ake nei, me te kaha o te hiahia mō te whakakapinga kawemai o ngā rauemi matū hiko, ka tere te tipu o te umanga hau hiko ā-rohe.
